Happy (7th Heaven)This aptly named dog always put a smile on the face of the show's characters and at least one viewer. "It always made me so happy (no pun intended) to see Happy at the end of the opening credits." (karrahbrooke)

Elvis (Miami Vice)Who says a pet has to be furry Elvis the alligator makes our list not only for being a cool pet, but also for exhibiting more charisma than the leads.

Paul Anka (Gilmore Girls)Lorelai's adopted dog was a bit nuts (who wouldn't be after hanging around that family), but hey, sometimes flaws are even more lovable. "He was adorable with all his idiosyncrasies!" (SpartanVartan)

Arnold (Green Acres)The most sophisticated swine on TV, Arnold was an avid TV watcher who could change channels and even play the piano. Top that, Lassie!

Brian (Family Guy)Many argue that some animals are smarter than humans. In the Griffin family, there's little argument. As confidant and partner-in-crime to Stewie, Brian is "literally man's best friend, with wit and style to spare." (MalTru)

Marcel (Friends)This feisty capuchin monkey helped Ross cope after losing his wife to another woman, but sadly had to be sent away to the zoo for his, um, overactive libido. Marcel became a movie star and Ross moved on to Rachel. Everybody wins!

FlipperThought of by many as Lassie in the water, Flipper proved you don't have to walk on land to be a heroic companion. "Flipper...stole my heart." (Westerns Fan)

Dino (The Flintstones)This one's simple: Yapping and face-licking aside, there's nothing much cooler than having a pet dinosaur.

Digby (Pushing Daisies)"Digby is the best! Every time I see that dog, I say, 'Awww' because you can tell how much he wants Ned to pet him with more than a fake hand. We don't have a dog, but Digby almost makes me consider getting one." (MaverickX)

Fred (Baretta)Another non-traditional pet, our readers still "have an affection for Fred the cockatoo." (dagal). Trivia note: The bird that played Fred had to learn English, as it originally spoke Chinese. They could have had fun with those subtitles!

Salty (Caroline in the City)As the only feline on our list (producers just don't choose cats that often, it seems) Salty still holds her own. Though this show might not become a "classic," at least it'll be remembered for this little furball.

Backup (Veronica Mars)"What a great dog! He didn't have a huge role, but he was always there when Veronica needed him the most!" (tazzy). What more could anyone ask for in a pet

Murray (Mad About You)Nobody said pets weren't clumsy, but Murray was so cute we didn't mind. "[Murray] was my all-time favorite. I loved when he would "get the mouse" and clunk into the wall!" (rmcp)

Eddie (Frasier)Some animals are so great, you don't even need the cast for laughs. "The best episodes were those that centered around Eddie." (FLAConnie) "I'm not a dog lover, but Eddie always cracked me up. What a scamp he was!" (Marci)
